Preventing salt crystallization using hemp-lime plaster in historical brick buildings

In this project hemp-lime is studied as a material for preventing problems with salt crystallization on historical masonry. Hemp-lime is a sustainable building material that exists of hemp shiv (the woody core parts of the hemp stem) and building limes. The material is diffusion open and has good thermal insulation properties. This continuation project will study the ability of the material to prevent salt related damages in masonry. For this purpose studies will be performed on a number of sample surfaces. The aim of this continuation project is to prevent salt damages on historical buildings while improving their energy efficiency.
